## Is 699 a perfect square number?

A number is a perfect square (or a square number) if its square root is an integer; that is to say, it is the product of an integer with itself. Here, the square root of 699 is about 26.439.

Thus, the square root of 699 is not an integer, and therefore 699 is not a square number.

## What is the square number of 699?

The square of a number (here 699) is the result of the product of this number (699) by itself (i.e., 699 × 699); the square of 699 is sometimes called "raising 699 to the power 2", or "699 squared".

The square of 699 is 488 601 because 699 × 699 = 6992 = 488 601.

As a consequence, 699 is the square root of 488 601.

## Number of digits of 699

699 is a number with 3 digits.

## What are the multiples of 699?

The multiples of 699 are all integers evenly divisible by 699, that is all numbers such that the remainder of the division by 699 is zero. There are infinitely many multiples of 699. The smallest multiples of 699 are:

## How to determine whether an integer is a prime number?

To determine the primality of a number, several algorithms can be used. The most naive technique is to test all divisors strictly smaller to the number of which we want to determine the primality (here 699). First, we can eliminate all even numbers greater than 2 (and hence 4, 6, 8…). Then, we can stop this check when we reach the square root of the number of which we want to determine the primality (here the square root is about 26.439). Historically, the sieve of Eratosthenes (dating from the Greek mathematics) implements this technique in a relatively efficient manner.

More modern techniques include the sieve of Atkin, probabilistic algorithms, and the cyclotomic AKS test.
